Start with songs everybody knows
A strong first song lowers the temperature in the room. Go for a chorus people can enter without checking the screen every two seconds: ABBA, Queen, Whitney Houston, Oasis, Britney, Fleetwood Mac, or the dependable chaos of Mr. Brightside.
The opening track is not the moment for a seven-minute deep cut. It is the social handshake. Once the room trusts the queue, you can get stranger.
